Abstract

A wear-resistant hollow stell ball for E-type coal mill was produced by lost foam casting process. Two pouring schemes including the top pouring and the side pouring were designed. The filling and solidification of the two schemes were simulated by the Huazhu CAE software. The simulated results were analyzed comparatively. And the experiment results were well in agreement with the simulated ones. The advantages and disadvantages of producing large wear-resistant hollow steel ball with lost foam casting process were described.
